Perhaps, it should be noted that the format that Bill decoded was used from 1957 onwards.
F - Flint, MI plant
12 = Dec
14 = 14th
B = 235 Passenger w/Powerglide (was this code used through 1962/63?)
(it should be noted that a Powerglide transmission was available as an option w/235 in some small trucks in the early 60s; I think its code was JB)?
